ToaZZ whom it may concern:

Be it known that 1, HERMAN E. WHIT- inc, of Palmyra, in the county of 1V ayne I and State of New York, have invented a certain new and useful Vaporizer for Internal-Combustion Engines, of which the following is a specification.

My invention has for its object the proction of a particularly simple and ei'licient oorizer or carburetor for inter "on engines, in which the aid fuel to be mixed with aispondingly with the volt sing through the vaporizer or during the opening and c osing or. valve; and to this other end sists in the combinam" 3 cc hereinafter set forth a clai o describing this invention reference is rs designate corresponding parts -le views.

Figure 1 is a .vertical sectional view of one embodiment of my vaporizer, the throt tle valve being shown as open. view similar to Fig. 1, partly broken away and parts being omitted, showing the positions of the shiftable nozzle member and the throttle valve when said valve is partly closed.

lathe illustrated embodiment of the invention 1 is the body or casing of the vaporizer or carbureter which contains a carbureting chamber having a conical or contracted wall 2. A fuel discharging'nozzle is arranged in the carbureting chamber and v may comprise a shiftable atomizing member 3 which shifts axially of a fixed member The shiftable member 3 preferably is in the form of an open-ended sleeve surrounding the fixed member i and said member 4. slidably fits in the member 3, the upper open end of the latter forming the atomizing opening. A choke chamber 5 may surround the atomizing nozzle, and move with the member 8 in order that the exit end of the nozzle will be always located substantial at the narrowest portion of ChO IQ cha; her, and said choke chamber 5 this instance is connected to the shiftai e member 3 by suitable webs 6. The inner iii-zed 111Gl1l ber i of the atomiraing nozf. ihly is carried by brid:e the air inlet carbnreter Specification of Eitters Patent.

member may communicate at its lower end with a conduit or passage :10 extending lengthwise of the bridge 7 The receiving member 11 for the liquid fuel may be the ordinary float chamber which communicates at its lower end at, 12 with a suitable source of supply of fuel. The float 13 within the chamber tends to maintain the level of the fluid at substantially the exit end of the nozzle when the nozzle is in its lowermost position as shown in Fig. 1. The float chamber may however be dispensed'with. 4

As here shown the conduit or passage 10 may communicate with a valve chamber. 1 and the receiver 11 also may communicate with the chamber 14 through a conduit 15 which includes a stand pipe 16 extending upwardly into the valve chamber 14, the stand pipe 16 being of large diameter compared with the passagelO and having a contracted exit end 17. The contracted stand M In the illustrated construction a needle;

valve 19 is located within the chamber 14, for openin and closing the upper end of the stand pipe 16, the valve being held in. its closed position'by a spring 20 and being provided with a piston 21 fitting the valve chamber. During the suction strokes of the piston of the engine to which this vaporizer is attached, the valve 19 will be raised from its seat to permit the flow of the liquid fuel out of the stand pipe and into the passage or conduit 10.

A throttle valve 22 may be employed for controlling the flow through the carbureting chamber, the valve preferably having a stem formed with a slotted head 2a in which woks a pin 25 carried by a crank arm. 26 mounted on a rock shaft 2'? which extends outwardly through the body of the vaporiz -r and which is connected by a link 28 to a suitable operating handle shown. The shaft 2? also be *onnected to the choke chamber and the movable member or seen u i nozzle order that the throttle d the choke chamber and the erafitbe zzle-..j; H

ated synchronously. Theseconnections'preferably comprise a link or pitma'n 29 having a strap or ring '30 at one end-which incloses an eccentric cam 31 rigid with the rock shaft 27, and is connected at its other end to one arm of a lever 32, pivoted to a depending bracket on the body 1 at 33 between its ends,

and the other arm of the lever is connected to a 'link 3a which is connected to a pin 35 extending into the base of'the choke chamber through a slot 36 in the body 1. Obviously 'as the rock shaft 27.. is operated, the throttle valve 22, and the choke chamber 5 v and the movablememberfi of the nozzle will also be operated. However, it will be obvious that the choke chamber 5 may be omitted, and also that said chokechamber is not neces arIly shiftable with the movable 1nem-'- a purifying and mixing device, said;

devicecomprlsing preferably a dust catch ing chamber 87 located below the throttle vaflve- 22 andaround the mixingchamber and; filtering device 38 above the throttlevalve 22. The dust-catching chambercom tainsa suitable'p fd 39in which a liquid. is

contained, forcatching the dust, and the filtering and mixing device 38 comprises plates lO, l 1 ,and.,42 formed with openings having portions spaced apart and adapted to receive between them a filtering material as asbestosand the like. The throttle valve 22- preferably is formed cup shaped in order to. deflect the incoming charge downwardly i-nto the dust catching chamber whence it 1 passes upwardly around the valve through the filtering and mixing device through a.

chamber 43 inthe upper'part of the body,

thence out through a nipple 44 by means of which the body of the vaporizer communieates with the inlet pipe of the engine. It

f will be understood, however, the filtering device may be omitted and any other form of .throttle valve may be employed. 1 As here shown the upper portion of the body ofthe vaporizer, that is theportion confining the chamber 43 .is' detachable from the major part of-the body and is secured thereto in any suitable manner, such as ordie nozzle a 1d-causes.carburizationzto take place.

'This charge, which necessarilypccntams a} number of globules ofgasolene,a-enters into the-bell-shapedthrottle. 22 which acts ,as :1.

heme and causes the charge to retiirn upon "itse1f, thus producing a mixing action and breaking up a great many of -the globules within themixture. The heavy solid particles will be deflected by the-baffle onto the dust catching pad 39. After the mixture has been returned upon itself, it passes through theperforated chamber '38, the remaining globules being deposited-on the jvalls of the openings in said chamber or be- 1ng caught by the asbestos until sufficient air has mixed with the globules to vaporize them. The asbestos also acts to-collect dust and, at the'same-time, is not'consumed or burned by a back fire. Thescreen 4:1 PI'G. vents. the back fire reaching the fuel dischargingnozzle 3, 4. 'Of course, when the' engine is started, the suction acts on the valve 19 to permit a fiow of fuel to the nozzle. 1;The nozzle is extensible and, in this way, the, supply therefrommay be made to correspond to the s eed of the engine.
